8 volt battery

[JimFord850]

Are there any problems using an 8 volt battery in a Ford 850 positive ground 6 volt system? I have been told no problem and also not to do it.

Is the 8 volt put on a charger at 6 or 12 volts?

You need 9.6 volts to charge an 8 volt battery.the tractors generator wont charge it.fix your 6 volt system.

#1 they do not make a charger for the 8 volt battery's so no way to charge them correctly.#2 your charging system will not charge it unless you have thing worked on to make it do that and that can cost big $$. #3 at best an 8 volt battery is a band aid fix for other problems. Stay with 6 volts or switch it over to 12 volts and be done with it and save your self the head ache of the 8 volt night mare

bad idea.

people that told you it was fine aren't your friends .. I wouldn't go to them for any more bad advice.

fix the 6 or go to 12.

easy to get 6v or 12v chargers. when's the last time you walked into a store and found an 8v charger for anything other than a kids race car?

think yer coil and points will like the extra punishment?

think yer 6v lamps will like 9+ volts?

Thanks for the info. I'll either fix my problems with the 6v or go to a 12v. Probably have to take a couple of those former friends off my Xmas card list.

To convert your 12v charger into an 8 v, you need a variable transformer. By reducing the input AC voltage to any old charger( not the modern chargers with auto shutdown) , you will reduce the output too. The electrical potential of any lead acid battery is 2.2v/cell. An 8v battery has 4 cells, that is 8.8v. Any voltage greater than that will charge the battery. I connect my charger to the battery, slowly increase the input acv and watch the ammeter. Charging at 10 amps won't hurt. BTY, my variable transformer's output is from 0-150 vac and it is about 50 years old. It was used by an old TV tech. Another trick, which may take longer to charge is to use a resistor to use up some of the voltage. I have used an old 12v seal beam head light, installed it in series with the battery, connected the neg of the charger to the battery, the + of the battery goes to one side of the seal beam. The other side of the seal beam goes to the + of the 12v charger. This will act like a trickle charger. The seal beam limits the flow of the current. One time all I had was about 250 ft of 16 awg wire. Used it as a resistor to limit the current while charging a small battery. You need to experiment with different things to find the resistance needed to give you the charging rate you desire and not over heat the resistor in the process. good luck. george
